Hi,

I got Length of 'group' must equal number of columns in 'counts' with the below code.

I know this is over 5 years old, but I just had the same problem and found an odd fix for it. I was running glimmaMA with a DESeq2 object and getting the same error, but in my design for the DESeqDataSetFromMatrix my group variable was called GROUP and for whatever stupid reason, renaming it to group made it work.

Have you tried the solution I suggested previously?

   read counts for each gene for edgeR
